PROBLEM:  (QAR 52528)		 (Patch ID: OSF415-400290)
********
This patch fixes a problem where the lpq command causes the program to crash
(Memory fault). The problem is caused by lpq running until a print queue
buffer in memory is overwritten. The following is an example of a core dump:

********
This patch includes no new print system features, but improves the overall
print system as follows:
        
o  Prevents race conditions that caused problems starting and exiting the
   line print daemon.

o  Fixes problems that caused print queues to hang.
        
o  Efficiency is improved.  lpq can reliably determine when lpd is not
   running, preventing the initialization of too many instances of lpd when
   many lpr commands are issued simultaneously.  This information is used by
   Pathworks/ASDU.

o  Logging is improved.  All errors or unusual events are logged as lpr.info
   or greater severity.  Messages for infinite network tries will no longer
   increase the size of lpr.log.  All lpr.log messages are tagged with the
   severity, to distinguish errors clearly to the Administrator and to
   technical support.
           
o  Loss of protocol messages is fixed due to improved reliability of network
   I/O.
